assuming point loading for beam calculation would a reasonable first

You will end in a too big possible load. Because the part between the two
wheels will only partially contribute to the stiffness. Now the guess is
how much. *I* wouldn't guess that.
The other approach to calculate only a strip as wide as a tire is will end
in a too stiff plate. Maybe double the tire width? Or threefold?

(I wonder what people did before F.E. analysis?)

It can be calculated and it has been done. The results were printed in
books. Slabs are a common problem for floors in buildings and that is
exactly what those books have been printed for.
